How to Preview ZIP and RAR Archive Contents on Mac Without Extracting

Why This Is a Narrower Problem Than It Looks

Our own guide to previewing files on Mac without opening them already covers the general shape of this gap: Quick Look treats archives the same way it treats folders, as one opaque item rather than something to browse. This post exists because archives have their own extra wrinkles that a general guide can't spend enough time on. ZIP and RAR behave differently from each other on a stock Mac, a free tool and a paid one solve different halves of the problem, and the honest answer for "which one do I actually need" depends on whether you want to look inside an archive or extract the whole thing.

What Quick Look Actually Shows on a ZIP

Select any .zip file in Finder and tap the space bar. What comes up is a small floating card: a generic grey document icon, the file's name, and its size on disk. That's the entire preview. There is no file count, no folder structure, no indication of whether the archive holds one PDF or four thousand photos. Option+Space to go full screen doesn't add anything either, the card just gets bigger around the same icon. We re-ran this on macOS 26 Tahoe on October 7, 2026, and nothing about it has changed from earlier macOS releases.

This matches how Quick Look handles folders, and for the same underlying reason: an archive is a single file as far as the operating system is concerned, and Apple's built-in Quick Look generator for it doesn't look past the outer wrapper. Double-clicking the ZIP is still the fastest built-in path to seeing what's inside, since Archive Utility decompresses it into the same folder automatically. The problem is that "fastest built-in path" still means committing disk space and clutter to find out the archive was the wrong one.

RAR: Why macOS Doesn't Open It at All

ZIP at least gets a fallback: a bad preview, but a working double-click extraction. RAR gets neither. Archive Utility only understands ZIP, TAR, and a couple of gzip and bzip2 variants, and RAR was never added to that list. Double-click a .rar on a Mac with nothing else installed, and Finder either offers to search the App Store for something that can open it, or sits there doing nothing useful.

This hasn't changed with 26 Tahoe or the newer 27 Golden Gate release, and there's no indication Apple is planning to add RAR support natively. RAR is a proprietary format owned by win.rar GmbH, and every working RAR implementation on Mac, including unrar, the command-line decompressor most third-party apps build on, exists because the format's creators publish a free decompression-only specification. Compressing into RAR format on Mac genuinely requires a paid license from WinRAR; opening one doesn't.

The Unarchiver: Free, but It Extracts, Not Previews

The Unarchiver is the tool most people land on first, and for good reason: it's free, it's been on the Mac App Store for well over a decade, and version 4.3.9, the build currently listed, opens ZIP, RAR (including the newer v5 format), 7-Zip, TAR, StuffIt, LZH, ARJ, and a long tail of older formats most people will never touch. Install it, and double-clicking a RAR file that previously did nothing now extracts it in place, the same way ZIP already worked.

What it doesn't do is let you look before you extract. There's no browse screen, no file list, no Quick Look integration in the free app itself. Double-click still means "decompress now." A companion app from the same era, The Archive Browser, once added exactly that: a browsing window plus Quick Look support for peeking at individual files inside an archive. We could not confirm a recent update to it, and several third-party app trackers list it as discontinued with no update since around 2017, so we're not recommending it here as a current option. Treat any copy you find of it as unmaintained.

Keka: Browse Before You Extract

Keka solves a different half of the problem. It's free as a direct download from keka.io, donation supported, and also sold on the Mac App Store for $6.49, a price we confirmed live today through Apple's own lookup API; buying it there adds automatic updates and supports the developer, but it's the identical app either way. The current build, version 1.6.8, shipped September 24, 2026, and its release notes show active maintenance, including an update to UNRAR 7.23 for RAR extraction and several small fixes to how browsed archive contents get extracted.

The part that matters for this guide: open an archive with Keka instead of double-clicking it (which still extracts immediately, same as The Unarchiver), and Keka opens its own window with a file browser showing everything inside, nothing written to disk yet. From there you can select just the files you actually want and extract only those, leaving the rest of the archive compressed. It supports RAR through the same bundled unrar binary, so this works on .rar files too, not just ZIP and 7Z.

What it isn't: a Quick Look extension. You have to open Keka itself to get the browse view. There's no space-bar shortcut for it, and pressing space bar on an archive with Keka installed still shows the same bare Quick Look card described above, since Keka doesn't register anything with Quick Look.

Where Quick X Folder Preview Fits In

We build Quick X Folder Preview, so read this section as the vendor talking. Its Archives extension is one of 13 Quick Look extensions the app adds, covering ZIP, RAR, 7Z, TAR, GZ, BZ2, XZ, JAR, WAR, IPA, and APK. Press space bar on any of those and you get the full file tree inside, filterable as you type, with nothing extracted to disk. Double-click one file inside that listing, and it opens or Quick Looks just that single file, the one capability none of the other three tools in this guide offer from the space bar.

Where it loses. It is not an extraction tool. If what you actually want is every file from the archive unpacked and sitting in a folder, Keka or The Unarchiver still does that job, and ours doesn't replace them, it sits upstream of that decision. It also can't open a password-protected archive any more than Quick Look itself can, for the same reason: there's no password field in a Quick Look pane. And like every tool here, a nested archive, a ZIP inside another ZIP, shows up as a single file in the listing rather than something that expands automatically; you'd still open that inner file on its own to look further.

The Bottom Line

Quick Look was never built to look inside an archive, and nothing about recent macOS releases has changed that. ZIP gets a working, if blind, double-click extraction. RAR doesn't even get that much without installing something. The Unarchiver fixes the RAR gap for free but still asks you to commit to extracting before you see anything. Keka adds a real browse-first window, free or for $6.49, if you're willing to open a separate app to use it. If you want that same browse-first view without leaving Finder, from the space bar, that's the specific gap a Quick Look extension for archives is built to close, ours included.
